This work was aimed at studying the phase structure and evolution of polypropylene (PP)/poly(ethylene-1-octene) copolymer (PEOc) blends with droplet/matrix morphology using scanning electron microscopy (SEM) during quiescent molten-state annealing process. The structure parameters, such as the area diameter, d (p) , and number average diameters, D (n) , of the dispersed phase in PP/PEOc blends were calculated by pattern analysis of SEM images. Moreover, the potential fractal behavior of the phase structure and morphology of PP/PEOc = 80/20 blend during the process was discussed. The histograms of obtained at various annealing time fell on a master curve, demonstrating the self-similar growth of the phase structure of the blends during quiescent molten-state annealing process.
